Email client · 100% local AI
Superhuman's speed. No noise, no $30 a month, and no one reading your email.
QuietMood separates what matters from the noise using explainable rules and, only when it's actually needed, an AI model that runs entirely on your machine — never on a server we operate. We don't run product servers: there is nowhere for us to read your email even if we wanted to.
macOS · Windows · Linux — signed binaries, no account required for the free plan.
How it works
Three steps, in this order. AI is the last resort, not the first.
-
Explainable rules first
Known sender, subject-line patterns, your own history of "mute emails like this." Measured on a real inbox: 83% of email is resolved this way, without calling any model. Fast, deterministic and auditable — you can see exactly why something got classified the way it did.
-
Local AI only when it's needed
The remaining 17% goes through a Gemma model running on your machine: does this actually matter? is it a bank charge? can it be summarized in the digest? The model never leaves the device, neither does the email it's reasoning about.
-
One digest, not an alarm
Low-priority email gets grouped into a daily summary. Your main inbox stops being a list of everything that arrived and becomes a list of what actually matters.
The problem is measurable — so we measured it
Before writing a single line of marketing copy, we measured a real 200-email inbox.
-
Local AI (Gemma), not the cloud
The generative model runs on your machine. There is no QuietMood server to send your email to for classification or summarization.
-
Offline semantic search
"That hotel receipt from March" finds the email with your wifi off. No mainstream email client does this, because they all depend on an index living in someone's cloud.
-
Movements: bank charges extracted for you
Transactional emails from your bank turn into a readable list of charges, without you opening each one.
-
AI-assisted drafting, also local
Reply suggestions generated by the same local model — no call to an external API in between.
-
Structural privacy, not a policy
No telemetry, no analytics, no remote crash reporting. The app's list of network connections is short on purpose — you can read the whole thing below.
-
Real deletion
"Free local data" performs an unrecoverable, on-device wipe, not a soft delete. Since we collect nothing, there's no copy on some server to ask us to delete either.
Privacy isn't a promise. It's a list.
This isn't marketing copy summarizing our privacy policy: it is, literally, the complete list of network connections the app makes. There's no fine print because none is needed.
Network connections QuietMood makes:
-
Your email provider (Google/Gmail via the official API with OAuth, or your IMAP/SMTP server): to read, send and organize your own email. It travels encrypted (TLS) between your device and your provider, with no intermediaries.
-
AI model downloads (one-time, from public repositories such as Hugging Face): the app downloads the model it then runs locally. No personal data is sent in that download.
No other network connection exists.
No analytics, no telemetry, no remote crash reporting, no QuietMood backend. Your credentials (OAuth tokens or app passwords) are stored only in your system's secure storage (Keychain, Keystore, Secret Service, Credential Manager) and are never sent to any server we operate.

An honest comparison with Superhuman
No inflating ours, no downplaying theirs.
| Feature | Superhuman | QuietMood |
|---|---|---|
| Price | $30/month ($360/year), single plan | Free forever (1 account); optional premium still being defined |
| Where the AI runs | On Superhuman's servers | On your machine |
| Who can read your email | You and Superhuman's infrastructure | Only you |
| Search with the device offline | No | Yes, semantic |
| Bank charge extraction | No | Yes (Movements) |
| Business model | Mandatory subscription from day one | Freemium by feature limits, not by a countdown timer |
| Mature mobile apps | Yes, years of polish on iOS/Android | Still being built |
| Team features (shared snippets/stats) | Yes | Not the focus — QuietMood is for your inbox, not your team |
Where Superhuman still wins, in our own opinion: mobile apps with years of polish and features built for teams. QuietMood is young software built by one person; the bet isn't to fake parity everywhere, but to move faster on what we actually chose to build.
Pricing

Superhuman charges $360 a year for AI that runs in their cloud. Our premium plan — once we announce it — will cost a fraction of that, because the AI runs on your machine, not ours: we don't have that server bill to pass on to you.
Frequently asked questions
Do I need an account or subscription to use it?
Not for the free plan: 1 email account, rule-based filtering and a daily digest, with no time limit and no credit card.
Where does the AI run?
Entirely on your machine, with a Gemma model served by LiteRT-LM. We don't run our own product servers: there's nowhere for anything to run in the cloud even if we wanted to.
Does it work with Gmail?
Yes, via Google's official API with OAuth. Also with any provider over IMAP/SMTP.
What network connections does the app make, exactly?
All of them are listed, with no exceptions, in the "Privacy" section on this same page and in the full policy.
What happens to my data if I uninstall the app?
It lives only on your device. "Free local data" performs a real, unrecoverable wipe whenever you ask for it, and uninstalling has the same effect.
When can I download binaries?
There's no signed public build yet. Join the waitlist and we'll email you as soon as one exists.
Be among the first to try it
There's no self-hosted form backend yet — that would be a privacy promise broken before we even started. Email us and we'll let you know as soon as there are binaries.
